“…No pycnostigmine specimens have been collected in the Mesic intervening areas. Masarine wasps (Vespidae) also exhibit this biogeographical pattern (Gess 1992). Interestingly, 4 genera of masarine wasps are shared between the two areas; the Palaearctic Region has one endemic genus and the other three genera are endemic to southern Africa, suggesting a similar historical evolutionary driving process for both groups of wasps.…”

“…The historical distribution of pycnostigmines, as did the rest of the fauna exposed to these changes (Grubb 1999;Grubb et al 1999;Vrba 1992), followed suite, experiencing phases of being alternately continuous and disjunct, culminating in the current phase of vicariance dictated by habitat and environment. This arid adapted vicariance is evident in a number of contemporary faunal distributions, such as butterflies (Carcasson 1964), masarine wasps (Gess 1992), flies (Bowden 1978), mammals ) and plants (White 1983).…”

“…The pollination system across the family is thought to be unspecialized (Struck, 1992(Struck, , 1994. Nevertheless, evidence of specialized insect visitors has also been found (Gess, 1992;Struck, 1995), with flower colour being one of the main factors influencing insects in their choice (Scodanibbio, 2002). Differences in the geographical distribution of flower colours are particularly evident in the sister taxa D. bellidiformis subsp.…”

Phylogeny of the Dorotheantheae (Aizoaceae), a tribe of succulent annuals

Dorotheantheae (Aizoaceae) is a small tribe of succulent annual herbs with flat leaves belonging to the generaAethephyllum, Cleretum and Dorotheanthus, which are endemic to the winter–rainfall region of South Africa. Several species are well–known for their conspicuous and striking flowers but others possess very inconspicuous flowers. Analysis of molecular data from combined plastid and nuclear sequences shows that Dorotheanthus is monophyletic while Cleretum is diphyletic, since the two species of Cleretum with lyrate leaves are most closely related to the vegetatively similar, monotypic Aethephyl–lum. In the absence of clear, diagnostic characteristics for separating Cleretum and Dorotheanthus, a revised classification for the Dorotheantheae is proposed in which the tribe consists of a single genus, Cleretum. Within Cleretum, we recognize 14 species, by raising/re–instating two subspecies to species rank and including two that are still undescribed. The major clades occupy distinct climatic and edaphic niches. Repeated shifting from large to small flowers may indicate changes in the breeding system. Since succulence in annuals is rare in the winter–rainfall region of southern Africa, we compare patterns of distribution between Dorotheantheae and the other leaf–succulent annuals in the region, namely in Mesembryanthemum (Aizoaceae) and in Crassula (Crassulaceae). We find that similar to the non–succulent annuals of the Poaceae and the Brassicaceae in this region, the annual species of Mesembryanthemum show a preference for arid areas. In contrast, in Dorotheantheae and in Crassula the hot–spots of diversity lie mainly in the wetter parts of the winter–rainfall area, with a decrease in the number of annual species northwards to the arid, winter–rainfall areas of the Richtersveld and the southern Namib.

“…This is within the size of ranges of other Afrotropical and Palaearctic species of Ceramius, which have a relatively narrow range (areas of 26 species ranging from 0.1x10 4 to 22x10 4 km 2 , estimated after Gess, 1992and Mauss, 1998. In the Afrotropical region, the degree of endemism of the markedly oligolectic species of Ceramius seems to be correlated with their plant association (Gess, 1996: 25, 41).…”

Ceramius hispanicus Dusmet appears to be restricted to an area of ca. 21x10 4 km 2 basically in central and north-eastern Spain. The species has been recorded from 32 localities. The altitudinal distribution ranges from 150 to 1300 m above sea level. C. hispanicus seems to be restricted to the meso-and supramediterranean story of vegetation. It has been recorded from 13 different vegetation series. The proportion of basophilic vegetation series of the localities is 65%. Climatic conditions at most of the localities can be characterised as moderately hot, with a cold period in winter and an annual mean precipitation of between 300 and 500 mm. The flight period of the imagines correlates with altitude, lasting from the beginning of May to the end of July.
